ABSTRACT

DISCLOSED IS A PROCESS FOR RAPIDLY CURING UNSATURATED POLYESTER MOLDING COMPOSITIONS WHEREIN THE UNSATURATED POLYESTER IS PREPARED FROM 2,2,4-TRIMETHYL-1,3-PENTABEDIOL. ACCORDING TO THE PROCESS OF THE INVENTION THERE IS CONTACTED AN UNSATURATED POLYESTER PREPARED FROM 2,2,4-TRIMETHYL-1,3-PENTANEDIOL, A MONOMER HAVING AT LEAST ONE OLEFINIC GROUP COPOLYMERIZABLE WITH THE UNSATURATED POLYESTER AND AN ADMIXTURE OF EQUAL MOLAR QUANTITIES OF SYTRENE AND MALEIC ANHYDRIDE.

Cl. 260-861 No Drawing. 5 Pages Specification Disclosed is a process for rapidly curing unsaturated polyester molding compositions wherein the unsaturated polyester is prepared from 2,2,4-trirnethy1-1,3-pentanediol. According to the process of the invention there is contacted an unsaturated polyester prepared from 2,2,4-trimethyl-1,3-pentanediol, a monomer having at least one olefinic group copolymerizable with the unsaturated polyester and an admixture of equal molar quantities of styrene and maleic anhydride.
